Another advantage in thls construction is that a comparatively short projector shaft `ma be used andl this results in lessening vi ration ofv the lparts in which it is mounted. The mechanism described exemplifies a machine in which the sand projector and its drivingr mechanism are mounted to move' longitudinally on .a pivoted `1support or jib and which is pivotally movable relatively to the jib. It will be understood that the projector is adapted to. project sand at high speed in. accordance with jour aforesaid patents.

The mechanism for `feeding sand tothe movably suspended projector comprises a .are secured on to pinion 42 which meshes wit 43 fixed to one end of the shaft 35'. hishopper32 which is supported by bracket 11 and over the receiving portion of an endless belt 33, which is disposed above the axis around which the jib swings and iscarried by a roller 34 whichis fixed to a shaft 35 vwhich is mounted in bearings which are `secured by bolts37 to jib members 12 and carried thereby. The case of an'electric mo..

tor 40 is rigidly secured to the socket-"9 and' the yshaft 4l of said motor is rovided with a a large ear motor and gearing serves to .continuously drive belt 33 to conveyjsand from the hop-v per 32 to the outer end of the jib. LA table 44 supported by brackets 45 is disposed un' der the upper reach of thebelt 33` to prevent it from sagging. Thellower reach vorf the belt is disposedv to runl between the tubular` members 12 of the j ib. -The sandv on the outwardlyl moving reachof belt 33 is displaced therefrom by 'a delector blade 46 which extends obliquely across the top of the belt.4

This blade is sustained in operative position"v over the belt by a bracket 47 -which is rigid. vwith the truck 14 so that the defiectorwilll .be movable with thetruck longitudinally 'of the jib and the belt This mechanism eir-v emplifies sand feeding mechanism compris#A fing 'a belt andlmea'ns-for displacingjsandf" 'pended claims, without departing from the 'from the bel-t at vdifferentpoints'.- 'y

The hub 20 of the truckfranie isfdisposed below and laterally of the' feedbelt and-is.

hollow, so'that the sand displayed from the belt by the deflectol' 46 will drop through' the hub. A hopper 48 is fixedly secured to the arms of the supporting bracket 18 to guide the sand discharged through hub 20 onto a feed belt 49 which is carried by rollers 50 and 51 which are mounted to move With the projector. The gearing for driving roller 50 to operate the feed-belt 49 maybe of the construction set forth in our aforesaid application Serial No. 452,068 and consists of lavarse 52 which are secured to the-tubular exten-` sion 26. The outer portion of said belt is adapted to deliver sand to the projector as Kset forth in our aforesaid patents `andapplication.

. In the present invention, the feed-belt 49 is movablewith the projector and a truck, on which the rojector is pivotally sustained, and anot er advantage of the present invention is that a comparatively short feedbelt may be here used.

-The operation of the improved machine will be as follows: Sand -inregulated volume will be delivered into chute 32 and conveyed outwardly by thevbelt 33 to the delector 46 which Will displace the sand from the belt so it will drop through i the hollow lhub 2() andhopper 48 onto the feed belt 49 which will convey it to the projector. In

filling'a flask beneath the projector, the operator,- may shift the projector longitu-` dinally of the jib in a rectilinear path, the truck being mounted tov move lonlgitudinally of the jib and may also swing the projector and its operating mechanism horizontally relatively to the truck and jib 12,' the pivotal connection between bracket 18 'and thel truck ment.` Whenever e projector is moved lon i-tudinally of the jib, the deflector 46 willgmove with the truck, so thatthe point of dis lacement of the sand from the belt 33 willJbe changed according to the position of the projector. -As a result, the point of displacement will be automatically varied with the shift of the rojector. By reason of delivery of the san to the hollow hub 20 of the truck, there is no operative change in the relative position of the sand feeding'- mechanism and, as a result, the sand will be continuously and regularly fed to the projec'tor in all of its positions.

The ,'nvenltion is not to be understood as restricted to the details set forth, since these may be-modiiied within the scope of the apspirit and scopeof the invention. j in Having lthus described the invention, what we 'claim asneyv and desire to secure by Let-- ters Paten-t is:
